摘要:
A method for managing a plurality of mobile units in a wireless cellular communication system having a plurality of repeater stations includes the step of receiving a signal on an uplink communication channel from a mobile transceiver unit at one of the repeaters. The method also measures at the repeater station a power level of the signal as received by the repeater station. The method further includes the step of transmitting a backhaul signal from the repeater station to the base transceiver station on a backhaul communication link, where the backhaul signal is transmitted at one of a plurality of discrete power levels providing an indication of the power level as measured by the repeater station.

A method for calibration of RF paths of a frequency hopping adaptive base transceiver station is provided. The method of calibration calibrates a wireless cellular telecommunication system with a frequency hopping adaptive base transceiver station including an adaptive antenna array with two or more RF traffic transceiver apparatus chains. The wireless cellular telecommunication system communicates with mobile units on a frequencies defined by a hop list. The method of calibration includes the step of periodically interrupting a frequency hopping process of the frequency hopping adaptive base transceiver station while calls are in progress. The method of calibration further includes the step of calibrating an antenna transmit path for a RF traffic transceiver apparatus chain at a frequency selected to include one or more frequencies in the hop list to determine a set of weighting parameters for the antenna transmit path at the one or more frequencies. A self-calibrating frequency hopping adaptive base transceiver station is also provided.

Method for transferring service for a mobile station call signal from a first base transceiver station to a second base transceiver station in a wireless mobile telecommunication system, while a call is in progress. The method can include receiving at a base transceiver station an access burst from a mobile station with a call already in progress and requiring service from the base transceiver station. Based on the received access burst, the base transceiver station can electronically steer a beam of an adaptive antenna array of the base transceiver station toward a location of the mobile station.
摘要:
A spectrally efficient wireless communication system that includes a plurality of base stations communicating indirectly with a plurality of wireless communications devices through a plurality of repeaters. The method can generally comprise communicating indirectly between a first base station and a wireless communication device using a first repeater and a first RF backhaul link. A control processor associated with the first base station can control a first smart antenna system. The system selectively configures the first smart antenna system to spatially isolate communications on the first RF backhaul from communications on a second RF backhaul of a second repeater.

A base transceiver station including a transceiver unit is provided. A method of calibration uses a transceiver unit to receive an RF signal, measure a calibration value, and transmit the measured value. The calibration value is used to determine weighting parameters to compensate for relative RF path phase delay and amplitude variation.

A method (100) for amplitude equalization in transmit and receive levels in a base station wideband transceiver (50) includes the step of assigning (102) a plurality of transmit and receive carrier frequencies to the base station wideband transceiver and the step of flattening (104) the power in the plurality of transmit and receive carrier frequencies in the plurality of base wideband transceivers using software amplitude pre-distortion.
摘要:
A method for managing a flow of information in an object oriented software environment. A master MOM (130) and at least a second MOM (135) can be initialized. A third MOM (140) also can be initialized. A change resolution (150), which includes data correlating to a change in a device in a system, can be automatically propagated from the second MOM to the master MOM. The change can be a change in configuration data or a change in a run-time state of the device. Data in the master MOM correlating to the change resolution can be updated. In response to the change resolution, a change publication (160), which includes data correlating to the change resolution, can be automatically propagated from the master MOM to at least the third MOM. Data in the third MOM correlating to the change publication can be updated.
